Answer:
c) 21.4
Step-by-step explanation:
9.5 times 1.5 times 1.5 is 21.375 or 21.4 rounded
Answer:
Step-by-step explanation:
1)First convert mixed fraction to improper fraction and them prime factorize


2)

3) 0.00706 = 7.06 * 
<em>4)</em> 144 = 12 * 12
12 = 6*2
6 = 2*3
Prime factorization of 144 = 2 * 3 * 2 * 2 * 3 *2
= 2⁴ * 3²
5) To find LCM, prime factorize 96 & 144
96 = 2 * 2 * 2 * 2 * 2 * 3 = 2⁵ * 3
144 = 2⁴ * 3²
LCM = 2⁵ * 3² = 32 * 9 = 288
6) HCF
105 = 7 * 5 * 3
135 = 5 * 3* 3 * 3
180 = 5 * 3 * 3 * 2 * 2
HCF = 5 * 3 = 15
7) 24 = 3 * 2 * 2 * 2 = 3 * 2³
36 = 3 * 3 * 2 * 2 = 3² * 2²
40 = 5 * 2 * 2 * 2 = 5 * 2³
LCM = 5 * 2³ * 3² = 5 * 8 * 9 = 360
HCF = 2² = 4
Difference = 360 - 4 = 356
8) Multiply each digit of the binary number by the corresponding power of 2, solve the powers and add them all
1111 = 1 *2³ + 1*2² + 1*2¹ + 1*2° = 8 + 4 + 2 + 1 = 15
Ans: 15
9) 36₇ = 102₅
10) 6.9163 = 6.916
Answer:
A 32.1
Step-by-step explanation:
Given two points
)
distance between to points = d = 
Now B is (-4,5) and A is (2,0)
So AB = 
C is (4,10)
So BC = 
D is (8,7)
So CD = 
E is (4,5)
So DE = 
and AE = 
Perimeter = 7.810 + 9.433 + 5 + 4.472 + 5.385 = 32.1
7x4x100=2800
7x4x1000=28,000
The first from right 8*3=24
72*3=216
216*3=648
648*3=1944
1944*3=5832
